Got code p0401 for my 2000 ford winstar sel and my engine light is on can anyone help me?


Hi there:
EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR.
You may notice drivability problems such as pinging (a.k.a. pre-ignition knock) when the engine is under load or the vehicle is at higher speeds. There may also be other symptoms.


A code P0401 most likely means one or more of the following has happened:
The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
There is a blockage in the EGR (tube), most likely carbon buildup
The EGR valve is faulty
The EGR valve may not be opening due to a lack of vaccuum

Possible Solutions: In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
Clean out the EGR valve and/or tubing to remove deposits
Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
Replace the DPFE sensor (with a good quality / OEM one)
Replace the EGR valve

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.


Thank you for using FixYa, have a nice day

I have a tropubleshooting code of P1405. On a ford Expedition 5.4l. Where do i fine the DPFE sensor (DPFE sensor upstream hose off or plugged.. aaECM detected EGR flow in a negative direction with aan


DPFE sensor failures are VERY COMMON on Ford vehicles. However, clogged EGR ports are also very common on 5.4L Ford engines. The DPFE sensor is located on the left side of the engine. It connects to two silicone rubber hoses that connect to the steel EGR tube coming from the back of the engine to the EGR valve. (See picture of the sensor below)

Another common failure is a DPFE sensor that has melted due to excessive exhaust back-pressure. If you find the DPFE sensor melted, suspect a restricted exhaust. (smashed tailpipe, clogged catalytic converter, etc..)

Need to find and replace the DPFE-15 sensor. Dealership diagnosed when service engine light came on and saaid this is what needed replacing. Problem is I do not know where to find it on the engine.


Exhaust Gas Recirculation (EGR) System The exhaust gas recirculation (EGR) system is designed to:
  • reintroduce exhaust gas into the combustion cycle.
  • lower combustion temperatures.
  • reduce the formation of oxides or nitrogen (NOX).
The amount of exhaust gas reintroduced and the timing of the cycle varies by calibration. Timing and volume are controlled by the following:
  • engine rpm
  • engine vacuum
  • exhaust system back pressure
  • engine coolant temperature
  • air charge temperature
  • throttle position
The EGR valve (EGR valve) (9D475) is vacuum-actuated. The vacuum hose routing diagram is shown on the Vehicle Emission Control Information (VECI) decal. The EGR system is a differential pressure feedback EGR Sensor system. Differential pressure feedback EGR Sensor is a subsonic closed loop EGR system. The differential pressure feedback EGR system:
  • monitors EGR flow rate by the pressure drop across the metering orifice located in the EGR tube.
  • uses a differential pressure feedback EGR sensor as the feedback device.
  • uses the EGR valve only as a pressure regulator, rather than a flow metering device.
  • controlled pressure is varied by the valve movement using vacuum output of the EGR vacuum regulator solenoid (9J459).
  • allows for a more accurate assessment of EGR flow requirements.

Differential Pressure Feedback EGR Sensor Removal
  1. Disconnect engine control sensor wiring (12A581) from Differential Pressure Feedback EGR Sensor.
  1. Disconnect Differential Pressure Feedback EGR Sensor hoses from EGR valve to exhaust manifold tube (9D477).
  1. Remove retaining nuts or bolts (depending upon application) and EGR Differential Pressure Feedback transducer.
Installation
  1. Follow removal procedure in reverse order.
  1. Tighten retaining nuts or bolts (depending upon application) to 5-7 Nm (45-61 lb-in).

Need location of the erg sensor 2000 ford ranger


The egr valve has two sensors. One is an EGR position sensor which is physically attached to the EGR valve. The other sensor is the DPFE (Delta Pressure Feedback EGR) sensor, commonly called the EGR pressure sensor. It's location varies depending on the engine you have. You can fine this sensor by following the vacuum hose on the EGR valve. It will be with in inches of the EGR valve. The sensor will be black (plastic) or silver (metal), have two or three vacuum ports and an electrical connection on it.

The vacuum pressure sensor is a high failure item on fords. Any Ford parts department will have one in stock, as well as some aftermarket parts stores.

The new sensor may not look exactly the same as the old part, but will have all the hook ups as the old one. You may also need to replace the vacuum hose to the sensor as well

Location of the egr sensor on 2000 ford ranger


The EGR pressure sensor is located within inches of the EGR valve. The exact location varies depending on the engine (2.5L, 3.0L or 4.0L). It is usually attached to the upper intake manifold with two small bolts.
